Hi Andy, I didn't check out SOLR-1316 yet, other then looking at the comments. Sounds more complicated than it should be, but maybe it's great and I really need to try it. Solritas uses TermsComponent, which should work well for individual terms (which country and city names are not, unless you tokenize them as single tokens). I don't think there is anything that will do everything you need out of the box. You can get autocompletion on the country field, but you then need to do a bit of JS work to restrict cities to the country specified in the country field. Actually, now that I wrote this, I think we did something very much like that with http://sematext.com/products/autocomplete/index.html . Finally, for dealing with commas or spaces as tag separators, you can peak at the JS in a service like delicious.com and see how they do it. Their implementation of tag entry is nice.
And here is another slick auto-complete with extra niceness in the search form itself, from one of our customers: http://www.etsy.com/explorer Otis ---- Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch Lucene ecosystem search :: http://search-lucene.com/ ----- Original Message ---- > From: Andy <angelf...@yahoo.com> > To: solr-user@lucene.apache.org > Sent: Sat, June 19, 2010 3:28:15 AM > Subject: Non-prefix, hierarchical autocomplete?
